  22 New Features
  23 ------------
  24
  25 -  Intel i965 "broadwater" DRI driver
  26 -  GL_APPLE_vertex_array_object - allows encapsulation of a set of
  27    vertex arrays in an object.
  28 -  GL_EXT_texture_sRGB - non-linearly mapped texture formats
  29 -  GL_EXT_gpu_program_parameters - addes a few new functions for setting
  30    multiple vertex/fragment program parameters with one call.
  31 -  "engine" demo
  32 -  updated fbdev driver and GLUT for fbdev (Sean D'Epagnier)
  33 -  many updates to the DRI drivers
  34
  35 Changes
  36 -------
  37
  38 -  The glVertexAttribARB functions no longer alias the conventional
  39    vertex attributes.
  40 -  glxinfo program prints more info with -l option
  41 -  GL_FRAGMENT_PROGRAM_NV and GL_FRAGMENT_PROGRAM_ARB are now
  42    compatible, in terms of glBindProgramARB()
  43 -  The GL_ARB_vertex_program attribute ``vertex.weight`` is now accepted
  44    by the parser, even though the GL_ARB_vertex_blend and
  45    GL_EXT_vertex_weighting extensions aren't supported. Allows Warcraft
  46    to run.
  47
  48 Bug fixes
  49 ---------
  50
  51 -  fixed broken texture border handling for depth textures (bug 6498)
  52 -  removed the test for duplicated framebuffer attachments, per version
  53    117 of the GL_EXT_framebuffer_object specification
  54 -  fixed a few render-to-texture bugs, including render to depth texture
  55 -  clipping of lines against user-defined clip planes was broken (6512)
  56 -  assembly language dispatch for SPARC was broken (bug 6484)
  57 -  assorted compilation fixes on various Unix platforms (Dan Schikore)
  58 -  glPopAttrib could restore an invalid value for GL_DRAW_BUFFER
  59 -  assorted minor fixes for 16 and 32 bit/channel modes
  60 -  fixed assorted bugs in texture compression paths
  61 -  fixed indirect rendering vertex array crashes (bug 6863)
  62 -  glDrawPixels GL_INDEX_OFFSET didn't always work
  63 -  fixed convolution memory leak (bug 7077)
  64 -  rectangular depth textures didn't work
  65 -  invalid mode to glBegin didn't generate an error (bug 7142)
  66 -  'normalized' parameter to glVertexAttribPointerARB didn't work
  67 -  disable bogus GLX_SGI_video_sync extension in xlib driver
  68 -  fixed R128 driver locking bug (Martijn van Oosterhout)
  69 -  using evaluators with vertex programs caused crashes (bug 7564)
  70 -  fragment.position wasn't set correctly for point/line primitives
  71 -  fixed parser bug for scalar sources for GL_NV_fragment_program
  72 -  max fragment program length was incorrectly 128, now 1024
  73 -  writes to result.depth in fragment programs weren't clamped to [0,1]
  74 -  fixed potential dangling pointer bug in glBindProgram()
  75 -  fixed some memory leaks (and potential crashes) in Xlib driver
  76 -  fixed a number of build issues on HP-UX (Christopher Bell)
  77 -  accum buffer didn't work with OSMesa interface
  78
  79 Internal code changes
  80 ---------------------
  81
  82 A number of Mesa program-related structs were renamed. For example
  83 *struct vertex_program* is now *struct gl_vertex_program*. All the
  84 effected drivers have been updated.
  85
  86 Ian Romanick updated the GL API dispatch code in a number of ways.
  87 First, many old/unused extensions were removed. Second, the static
  88 entrypoints for some extensions were removed. This means GL function
  89 pointers will have to be used more often (e.g. use
  90 glXGetProcAddressARB()).
  91
  92 To Do (someday) items
  93 ---------------------
  94
  95 -  Switch to freeglut
  96 -  Increase MAX_DRAWBUFFERS
  97 -  Fix linux-glide target/driver.
  98 -  Fix lambda calculation for frag progs.
